EDFA-WDM Optical Network Analysis
Optical network that apply wavelength division multiplexing (WDM) is currently widely used in existing telecommunications infrastructures and is expected to play a significant role in next generation networks and the future Internet supporting a large variety of services having very different requirements in terms of bandwidth, latency, reliability and other features. The purpose of this paper ...
متن کاملCost Effective Long Reach Hybrid WDM-TDM Passive Optical Network Using Bidirectional EDFA
Both the low cost and high capacity has become an increasingly significant aspect of network design. So this tutorial paper demonstrates a long reach hybrid WDM (wavelength division multiplexing)/TDM (time division multiplexing) PON (Passive optical network) system with dual pumped bidirectional Erbium doped fiber amplifier (EDFA). This architecture has a total reach of 115Km and EDFA provides ...
متن کاملOptical Network Design with Optical Constraints in IP/WDM Networks
In this paper we consider algorithms for the logical topology design and traffic grooming problem in WDM networks with router interface constraints as well as optical constraints. The optical constraints include restricted transmission range due to optical impairments as well as limits on the number of available wavelengths. We formulate this problem as an integer linear program which is NP-com...
متن کاملInvestigation of EDFA based 32 Channel C-Band Optical WDM System for Different Pumping Techniques
With the rise in demand for channel capacity, Wavelength Division Multiplexing (WDM) technique is employed in optical communication networks. Gain Flattened Erbium Doped Fiber Amplifier (EDFA) is used in optical WDM system to obtain a uniform output power level. The performance of EDFA depends on various parameters such as fiber length, pump power, pumping wavelength and pumping technique. The ...
متن کاملIP/WDM Optical Network Testbed: Design and Implementation
This work presents the design and implementation of an optical transparent IP/WDM network testbed. The implemented software allows the characterization of the transport, control and management planes of the network. Furthermore, it was developed a graphic user network interface for the client/management relation in the optical network. We adopted a centralized the control and management planes,...
